"by the skin of the teeth" fits this manga like skin.
A bunch of casters around the world narrowly erected a barrier to imprison a spatial reconstruction the size of a city punching a hole into the fabric of reality.
But man... I didn't expect an entire chapter on the catastrophe in the THIRD season of the manga, and the second chapter.
Now we even know how the prison was "made"... even if we don't what is made off.
Nightow-sensei came back strong, this new season will be a blast.
